ADDING AND RECORDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 553,331, dated January21, 1896.

V Application filed December 20, 1894. Serial No. 532,482. No model.)

To to whom it may concern:

Be it known that we, LEE S. BURRIDGE and NEWMAN R. MARSHMAN, citizens ofthe United States, residing at New York city, in the county and State ofNew York, have in.- vented a certain new and useful Adding and \VritingMachine, of which the following is a specification.

The object of our invention is to provide a machine that will print andadd figures by the operation of a stylus as exemplified in LettersPatent on type-writers granted to us on April 7, 1885, Nos. 314,996 and315,386, this invention being the outgrowth of that, and an adaptationof it modified to serve the purpose for which it is intended.

Referring to the drawings, Figure l is aplan View. Fig. 2 is a detailside View of the paperca-rriage as seen when looking at the lefthandside of the machine. Fig. 3 is a side elevation as seen when looking atthe lefthand side of the machine. Fig. 4 is a detail View of theescapement controlling the adding mechanism. Fig. 5 is a detail planView of the ratchet and pawl engaging the main wheel. Figs. 15 and 7 aredetail views of the escape ment controlling the carriage. Fig. 8 is afront elevation. Fig. .9 is a detail plan View of a portion of thestandard 2. Fig. 10 is a detail View of the inking device andtype-wheel, looking from the rear. Fig. 11 is a detail plan View ofcscapement, partially shown in Fig. 4. Fig. 12 is a detail View, on amuch larger scale, of an adding-wheel and tens-carrying mechanism. Figs.13 and 14 are views of an adding-wheel and its arbor, 850. Fig. 15 is adetail plan View showing the connection between the adding and thepaper-carriage frames. Fig. 16 is a side elevation, similar to Fig. 3,but on a larger scale.

1 is the base on which is rigidly secured the standard 2 and posts I},4, 5, 6, and 7. On the projections 10 of the standard 2, Figs. 1, 3, andi), is fulcrumed the frame 25 by shoulderscrews. Across the rear partwhere this frame is fulcrumed is fastened a cross-piece which serves tostrengthen the frame, and in the center of this cross-piece is fulcrumedthe stylus-arm 20, which projects through the slot 30, Fig. 8, in thefront of the frame 25, and at the outer extremity of arm is secured thestylus 27.

The type-wheel 31 and gear-Wheel 32 (see Fig. 16) are secured togetherand rotated on the screw 33, which enters a projecting lip of the frame25. (Shown in dotted lines in Fig. 8.) Below the stylus 27 on the arm 26is secured the rack 34,which meshes in the gear-wheel 32. The frame isheld upwardly by the spring 35. Two arms 36 are secured to the standard2, and rigidly support the letter-plate 37, Figs. 1, S, and 9, which hasten downward tapering slots or sockets, and opposite each a number,beginning with 0 on the left.

15y moving the stylus to the numeral desired the type-wheel will berotated, bringing the desired numeral 011 the type-wheel opposite theimpression-point, and by depressing the stylus it will enter a slot andbe locked from any side motion, thereby also locking the typewheel.

The type are inked by the felt roller 40, which is saturated with inkand rotates on a wire which is riveted to the small arm 39, which isfulcrumed to the arm 38, and the spring 41 causes the roller 40 to bearagainst the type, Fig. 10.

The arm 38, which carries the above-mew tioned arm and roller 40,rotates on the screw 33, which is also the fulcrum. of the type-wheel31, and the pin 42, which is riveted to arm 38, projects through aslotted guide-piece 11, which is rigidly secured to the post 3.

The normal position of the ink-roller is on the part of the type-wheel31 over the platen 51, but as the frame 25 is depressed (by depressingthe stylus) the roller rides away, owing to the pin 42 projecting intothe slotted guide-piece 11, and allows the type to strike the platen 51,Fig. 8, and upon the downward and upward motion will ink the typeopposite to the impression-point.

The carriage consists of the frame for carrying the paper and the frame00 containing the adding wheels and mechanisms. (See Figs. 8 and 15.)These two frames are joined together by a shoulder-screw 44, Fig. 15,and are supported in the front by being fast to the rod 4!), which islongitudinally movable through the opening in the post 4 on the rightand bears 011 the wheel 12 (see Fig. 8) fulcrumed 011 the post 3, and atthe back the frame is fast to the rod 48, which is longitudinallymovable through an opening in the standard 2 on the right and through anopeir ing in the post 5 on the left, Figs. 1 and 15. The two frames 50and and rods 48 and 49 will therefore travel as one carriage. Thiscarriage is propelled toward the right by the spring 47, (seen best inFig. 8,) which is coiled on the fulcrum of and bears against thecamshaped lever t5, to the free end of which is pinned a pitman 46,which in turn is pinned at its other extremity to the frame 50 of thecarriage, Fig. 8. Said carriage is returned to the left by the lever 15,as hereinafter described.

The escapement, which is for the purpose of allowing the carriage to goto the right a tooth at a time, consists of the rack 7 5, (see Figs. 6and 7,) which is secured to the rear of the frame 60, (see Fig. 1,) andthe split springdogs 76, (although made of one piece they act as two,)which are secured to the fiat face of the arm 77, which is pivoted tothe lever 78, which in turn is fulcrumed on the screw which supports theleft-hand side of the frame 25. (See Fig. 1.)

The dogs 76 are made of one piece of spring metal split in the middlepart way, and one half is screwed rigidly to the flat face of arm 77,while the other half has an outward spring the space of a tooth in therack 75, and which can be regulated by a screw 72.

The lever 78 has a finger key or plate 7 8 at its front extremity abovethe letter-plate to be used for spacing when no printing or adding isrequired, and it is also depressed at every depression of the frame 25by the pin 7 a, which projects from said frame 25 above said lever 78.The spring 7 9 bears the lever up. The dog 7 6 has an outward spring, sothat when the lever 78 is depressed the free half will spring out, andwhen returned to normal this free half will enter the next opening inthe rack and be pushed against the flat face of the arm 77, (by a toothof the rack,) as the spring 47 which propels the carriage is strongerthan the spring of the dog.

hen the carriage has gone the required distance to the right and isreturned to the left or first position (which operation will beexplained farther on) the dog 76 will ride over the teeth in therackthat is to say, the arm 77 will have an up-and-down motion from thefulcrum, and the spring 7 0 tends to bear this arm down, andconsequently the dog into engagement with the rack, Figs. 6 and 7.

The platen 51, which is on the rod a9, is hexagonal in form, as seen inFigs. 2 and 15, and is kept in position by the spring 52 bearing 011 oneof its sides or faces, Fig. 8. The rubber rollers 53 and 54: are inrolling contact with each other and serve to feed the paper forward,when rotated, in a manner well understood. They are rotated by means ofthe ratchet-wheel 55 and arm 56, which has a pawl 57 engaging in theratchet-wheel. This arm 56 is operated by the connecting rod or link 19,to which it is loosely connected, as will be explained farther on.

The paper is passed between the shield 58 and roller 53, and by turningthe rollers it will be guided between them and between the shields 59,which serve to keep the paper secure on the platen, Fig. 2. The papermay be in short lengths; but to avoid the constant entering and forother reasons we have shown a roll of paper 100 on a spool 101, the endsof which are supported in slots in the extremity of two arms 102 whichare secured to the base. The roll of paper is stationary; but there issufficient distance between the roll and frame for the paper to bend asthe carriage travels back and forth.

The adding mechanism consists of the adding-wheels 61, which are cutwith ten teeth and rotate on the rod 48, which has a keyway cut into it,Figs. 13 and 14, and between each two wheels 61 is placed a thin washer63, which has a tongue fitting in the keyway in the rod 48, to preventall the adding-wheels 61 from rotating together, and thereby avoid anyfrictional action of one wheel on another.

64: are anchoring-pawls which serve to bring and retain their respectivewheels 61 in a set position. They are cut at their extremities on twoangles which set in the teeth or between two teeth of the wheels 61, asshown in Figs. 3 and 16. The rod 82 serves as a hearing for said pawls,and the springs 65 tend to keep them in engagement with said wheels 61.The triggers 66, arms 67, and pawls 68 are the tens-carrying-overmechanism. On the left side of each wheel 61 (except the last on theleft) is a pin 62. (Shown clearly in Fig. 13.) The triggers 66 have therod fora bearing. The arms 67 have the rod 81 for fulcrum, and at theouter extremity of each arm a pawl 68 is fulcrumed and a spring 69 tendsto bear the pawl against the pin 70, Fig. 12. The springs 71 (seeFig. 1) bear the arms 67 up and the lower part of each trigger 66 restsagainst a jog or step 67 cut in the arm 67 and retains its respectivearm down, as shown in Figs. 3, 12 and 16.

The anchoring-pawls 61, triggers 66, and arms 67 all have tubes fastenedto them to increase the length of bearing on their supporting-rods andkeep them in proper positions. The springs bear against the triggers 66.

The upper part of the triggers 66 is between the adding-wheels 61 inline with the pins 62, so that when a wheel is rotated the pin 62 pushesout the trigger 66, causing the lower part of it to disengage itselffrom the arm 67, allowing said arm to spring up by the action of thespring 71, and the pawl 68, which is in line with an adding-wheel, willcause that particular wheel to rotate one tooth, as shown in full linesin Fig. 12. The arresting-point of the arm 67 is the rod 83, Figs. 3,12, and 16.

It will be seen that there are eight addingwheels and anchoring-pawls,but only seven triggers 66 and arms 67. The pin 62 of the firstadding-wheel to the right acts on the first trigger and that acts uponthe first arm, the pawl of which when let off acts upon the sec ondadding-wheel, and so on, so that the first adding-wheel to the right hasno arm in line with it, and the last adding-wheel to the left has no pinand obviously no trigger to act on.

The reading-line of the adding-wheels is the upper central line (seeFig. 1) and the pins 62 are set in aposition to act on the triggers 66as the wheels are rotated from 9 to 0.

The addingwheels 61 are rotated (except for carrying the tens) bythelarge gear-wheel 90, which is made as light as possible and whoseteeth project below the surface of the wheel sufficiently to mesh withthe teeth of whichever of the adding-wheels it is operating. Forinstance, if such a number as 321 is to be printed and added, the stylusis first operated to print the numeral 1, and as the large gear-wheel 90is at this moment in mesh with the units-adding wheel said units-addingwheel is moved to add one. Now, as the pa per-carriage and the framecarrying the adding-wheels all move as one carriage, the add ing-wheelsare moved toward the right the same distance (one notch of the rack asthe paper-carriage moves. This movement to the right, of course, bringsthe next addingwheel (the tens-wheel) into mesh with the gear-wheel 90,so that when the 2 of the number 321 is printed the second or tensaddingwheel is rotated (to add the 2) instead of the units-wheel. Of course itis easily seen that as the paper-carriage and the adding-wheels move tothe right the proper adding-wheel will be brought into mesh with theoperating wheel --that is, when the numeral 2 is printed theadding-wheels again move to the right, thus bringing the hundreds-addingwheel into mesh with the operating gear-wheel 90, so that when the 3 ofthe number 321 is printed the 3 will be added 011 the hundreds-addingwheel, and so on if a larger number is printed and added. This wheel 90is loosely journaled on the arbor 92 and has a pawl 98 mounted thereon,(see Fig. 5,) which engages with a ratchet-wheel 97, which is fixed tosaid arbor 92 and therefore rotates with the arbor as the latter isrotated by the flat coiled spring 91. (See Figs. 3 and 8.) Of coursewhen the arbor 92 and its ratchet-wheel97 are rotated by said spring,the wheel 90 is caused to rotate also, through the medium of the pawl98, as will be readily understood. hen the arbor is rotated in theopposite direction, the pawl 98 simply slips over the teeth ofratchet-wheel 97 in the usual manner. This wheel 90 is arrested by anL-shaped piece 29, which is rig idly secured to the right of frame 25and the projecting L of which is between the teeth of the wheel 90, asshown in Figs. 1, 4, and 8. hen the frame 25 is depressed, the wheel 90is freed from the piece 29 and is free to retate under the influence ofthe spring 91.

On the arm 26 is fulcrumed the arm 28, which has a finger projectingdownward in line with the teeth in the wheel 90, and the spring 36 bearsthis arm 28 against or parallel with the arm 26. Now when the frame 25is depressed the finger of the arm 28 will enter between two teeth inthe wheel 90, and as soon as the projecting L of piece 29 has passedbelow the teeth the wheel 90 will-be impelled by the spring 91, carryingthe arm 28 with it, the spring on the arm 28 being much lighter than thespring 91, until the arm 28 comes in contact with the set-crew 13 on thepost 3, where it will be arrested. (See Fig. 11.) hen the frame 25 isallowed to return to normal, the wheel 90 will have no motion, as theprojecting L of piece 29 will enterbetween two teeth before the fingerof arm 28 is above the teeth of the wheel. WVhen, however, it is abovesaid teeth, it (arm 28) will be impelled toward the arm 26 by the spring36. These two arms 26 and 28 each have an opening cut in them (see Fig.11) to allow movement without contact with the arbor 92.

It must be understood that the teeth of the letter-plate 37 that formthe slots or sockets before referred to, except the first on the left,are cut on the same gage as the teeth in the wheel 90, so that when thestylus 27 enters a slot in the letter-plate the finger of arm 28 willenter between two teeth in the wheel.

The different slots in the letter-plate cause the finger of arm 28 toenter the teeth in the wheel the required distance from the setscrew 13.Thus when the stylus enters the first cut on the right-hand end, whichis the 9, the wheel will rotate nine teeth before the arm 28 comes incontact with the set-screw13. When a O is to be printed the wheel 90does not rotate at all, as the arm 28, instead of going centrallybetween two teeth, willbe close to the one on the right-hand side and upagainst the set-screw 13, thereby preventing the wheel 90 from rotating.It will be noticed that the first slot in the letter-plate on thelefthand end is not equidistant with the others for that purpose.

The operating-arm 15 is secured on the shaft 16, which is supported bythe posts 6 and 7. lVhen this arm is drawn down by the handle it causesthe fiat coiled spring 91 to be wound up, whatever amount it may haverun out, through the agency of a chain 93, which connects theoperating-arm 15 to a drum 94 on the arbor 96, thus causing the latterto rotate, consequently rotating the miter-wheels 95 as the drum and themiter-wheels are fast to their respective arbors 96 and 92. The

drawing down of the arm 15 also causes the carriage to be returned tothe left-hand side of the machine, as said arm 15 bears against acam-shaped lever 45, which is connected to the carriage by the pitman46,11ereinbefore mentioned. (See Fig. 8.) It will also cause the paperto be advanced for a new line through the agency of the arm 18, which issecured to the shaft 16 and is connected with the operating-arm 56 bythe connecting-link 10. (See Figs. 2 and 16.) It will also cause thearms 67 to be reset or such of the arms as have been let off by means ofthe arm 20 (which is pinned on the shaft 16) bearing against the arm 21,which is loose on the same shaft and which has an inwardly-projectingarm or finger 23, which lies over all the arms 67. (See Figs-1, 3, 12,and 10.)

A spring 22 bears the arm 21 up against the pin 24: on the post 5 tokeep the arm or finger 23 normally above the arms. (See Fig. 8.) The arm15 is normally held upright by means of a spring 17 on the shaft 16.(See Fig. 1.)

The operation consists in moving the stylus opposite to the desirednumeral on the letter-plate and depressing it, which will cause thatnumeral to be printed on the platen 51, and the wheel 90 (and whateverwheel (31 it is in mesh with) to rotate that particular number of teeth.lVhen the hand and stylus return, the carriage will take one step to theright, owing to the movement of the spring-clogs 76 with rack 75, andthe next depression of stylus will cause a numeral of a higher numericalorder to be printed and added.

WVhen the desired number has been printed the arm 15 is drawn down,which will cause the carriage to be returned to. the startingpoint, thespring 91 to be rewound, the paper to be advanced to a new line, and thearms 67 to be reset, it let off during the rotation of the adding-wheels61.
